I agree with Hugh, I like your idea better. It would be easier to attach
to
if the sub was on various angles.

buoy
What's
the advantage of having the reel travel with the buoy instead of remaining
with the sub and unreeling from there?
Hi JT.
I don't see any advantage in having the reel attached to the buoy either.
It will just add weight and entanglement hazards to the buoy. Good idea on
marking the line to show depth.
Alan: My little sketch didn't show the release mechanism very well. My
thought was to use a spring loaded pin that keeps the latch on the buoy
closed. The "entrapped" pin in the thru-hull would push out the spring loaded
pin in the release mechanism, providing a positive lock on the buoy. The
thru-hull just needs to be a small one. I think a 3/8 inch nipple would be
fine with a 1/4 inch rod trapped inside with "O" rings to seal.
The valve would only be open for a few seconds to activate the
release.
Magnets might work but you still need a release mechanism of some
sort.
Lots of guys use a small hydraulic hand pump to activate the drop weight
latch. It would be fairly simple to add a valve and line to the pump to
activate the buoy release.
